GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic agonist of ghrelin, the gut peptide that binds to the growth hormone secretagogue receptor. Ghrelin has been shown to have two major effects: stimulating both growth hormone secretion and appetite. GHRP-2 has been extensively studied for its utility as a growth hormone secretagogue (GHS), with animal studies demonstrating its effects on GH release and food intake. It is of interest in research related to growth hormone deficiency, muscle wasting, and metabolic regulation.
